SeachemSC 10g POLYGUARD 0.4oz

My betta suddenly suffered from clamped fins and was hiding at the bottom of her tank. Sometimes she zoomed around hitting the glass. I couldn't figure out what was wrong. Main tank Ph was 7, ammonia was and nitrates were minimal, but after I cleaned the gravel it looks like the nitrites spiked a day later. I set up a small hospital tank (3L) with a pinch of aquarium salt. I tried different medicines with no effect every two days with water change to see which would help (melafix, pimafix, coppersafe, general cure). She had no change and I was worried, because five days in it looked like she was suffocating, could not swim and rested her body on a floating leaf, so I kept buying different types of medicine.The Polyguard gave noticable results after one day. I mixed this with aquarium salt and a small pinch of API General cure. She actually started swimming around little by little and didn't clamp her fins as much. The culprit also became more apparent on the second day of use; a whitish film was now falling off of her. It was extremely hard to see, I had to use a flashlight on her scales. She also became more alert and is swimming around peacefully. I did a full water change every second day and kept the temps between 80-82F.I had two 3L mini tanks, when it was time to change the water I set up the empty one as such: I mixed bottled spring water (distilled will be acidic). First, I dissolved the right measure of aquarium salt in a glass cup then dissolved the medicine together in the cup. Second, added preheated water between 80-82F to the 3L tank and kept a digital thermometer with a probe inside. Next, I tested the Ph of the tank water and made adjustments as necessary. Once temps were good and the PH was around 7, I added the salt/medicine mix from the beaker. Lastly, I prepped my betta to transfer from the old hospital tank to the refreshed one. I gave her 15 minutes to get used to the new tank before moving it to the heatsource. You may laugh at me, but I used what I had as a heater: a reptile heat mat with a thermostat (to maintain the temp), with a flat ceramic dish on top as a buffer underneath the 3L hospital tank (the tank was acrylic, so you can't use a heatmat directly underneath it, but you can use it with ceramic, and ceramic helps distribute heat evenly). I have some of the low watt aquarium heaters but they are not adjustable and sometimes got too hot--I didn't want to risk it. So I found my heatmat combo the most stable.So far so good--her behavior has improved. Now I have to get her to eat >(°^°)<tldr; My betta looked near death, nothing helped in 7 days, tried Polyguard with Aquarium salt in a hospital tank and noticable improvement after 24-36 hrs.

This was the quickest way to get medicine for a sickly fish I was taking care of. Within a couple doses, the fish was back to normal. It was easy to use. I wish it came in a smaller batch as I probably won't use the rest of it before it goes bad.

I was able to treat two 20-gallon tanks as recommended and I still have some left. The treatment worked like a charm and my fish are healthy and happy.

I got this for my Betta who rips his fins on aquarium decor from time to time. I had been using erythromycin for all of my fish when they got sick or injured. It seemed my Betta's fins would never heal all of the way back. With this medicine, thru were completely healed after 2 doses. I also used it on one of my female cichlids who got beat up by her tank mates. She was ready to go back to the big tank after 1 week of isolation & 2 doses of the poly.

I have several tanks. Albino Cory had red blotches in one tank and platy in another tank was hiding and appeared not well. I treated both tanks and I both fish recovered. Easy to use and works like a charm.

I used with paraguard and after a week my fish looks so much better, no more popeye (ick I used when Just started) Read instructions must be used 2 weeks at least and every 3 days. Is poder very small amout, comes atrached to the lid the little spoon fordesease. Turns the water blue but becomes normal after few minutes. Doesn't colorize my fish tank, but be careful could stain other things. One of this is enought for complete tratment in my 40 gallon fish tank and still have. Happy with this medicine.

I've fought with other medicines this is all I use now

I’m relatively new to the freshwater aquarium keeping hobby, however , over the last few months I’ve gained a wealth of knowledge, particularly in regards to the keeping & care of GloFish white skirt tetras.Unfortunately, this last critical lesson came too little, too late.Soon after I lost all 3 of our GloFish tetras within 48 hours after administering this product as directed, I began doing some research on the ingredients in Polyguard.I quickly discovered that the #2 ingredient, Malachite Green, is toxic to tetra fish.But NOWHERE on Sachems website, product info page, package insert, packaging, or bottle itself does it even advise caution when administering to this particular breed of fish, let alone the toxic effects it has on them.The product indicates it’s safe for freshwater and marine fish. It advises to keep away from children that it is intended for aquariums for ornamental fish only and not for human consumption.It goes on to state that PolyGuard™ is an exclusively in-water medication that can be stressful to plants and invertebrates (corals, mushrooms, shrimp, crabs, etc.). It should not be used in tanks that contain plants or invertebrates for this reason.And finally notes on their FAQ page on their site that Fish that are more sensitive to medications (scale-less fish, sharks, rays, eels, etc.) should be treated with care.Had they noted TETRA fish in that list, i’d have never purchased it, period. And that is just simply stating that it should just be administered with Care. Let alone failing to disclose that It’s completely toxic to these particular small, tropical fish.They also claim their product is easily removed with a carbon filter. That statement is 100% false.The toxic affects were almost instantaneous causing causing severe, almost paralyzing lethargy, disorientation, obvious loss of vision & blindness, loss of buoyancy & inability to swim, eyes bulging (some almost completely popping out of the socket) , excessive mucus production on entire bodies of the fish, violent thrashing, bleeding at the gills, rapid breathing in 2 of them, while labored breathing exhibited by the 3rd, finally resulting in suffocation & death.Despite quick action to remove the product by adding a new carbon filter into the tank, performing an 85% water change, (replacing with ideal parameter water conditions for these particular fish), adding freshwater aquarium salt to try to neutralize it, keeping PH slightly above 7, slowly reducing water temp to 76.1° & cutting all aquarium lights in effort to minimize the toxicity, the damaging affects were irreversible.The first fish died within 12 hrs, the second at 24 hrs & finally the 3rd I had to euthanize at 48 hrs b/c I could not stand to watch it suffer any longer & clearly there was no chance of recovering from these detrimental side effects.There is NO reason why a company that has been around over 40 years in the aquarium & fish keeping industry, does not have a warning or information listed regarding potential toxic affects & risks associated with some of the ingredients in their products.This is completely inexcusable & someone needs to be held accountable.
